Turn a Word document into clean, semantic HTML you can paste into a website, CMS or email tool — headings stay headings, lists stay lists, tables stay tables, and images are embedded in the file. The conversion runs entirely in your browser with the Mammoth engine; your document is never uploaded.
The converted document will appear here — a live preview first, with the raw HTML one tab away.
For bloggers, marketers and developers — Word drafts into web-ready markup without the paste-mess.

Convert Word .docx documents into clean, semantic HTML in your browser: headings, paragraphs, bold and italic, lists, tables, links and images are mapped to proper HTML elements — not the tangled markup Word itself exports. Preview the result, copy the HTML into your CMS, or download it as a file. Your document never leaves your device.
A press release drafted in Word: convert it here, copy the HTML into the website’s editor, and the headline is a real H1, the quotes are paragraphs and the contact table stays a table — no font tags, no mso- classes, no fifteen nested spans to clean up by hand.
The converter is Mammoth, the open-source library built specifically for this job: instead of mimicking Word’s page layout, it reads the document’s structure and style names and maps them to semantic HTML — Heading 1 to h1, List Bullet to ul/li, tables to table elements — and embeds images as data URIs so the HTML works anywhere. Anything it cannot map is listed in the conversion notes under the preview.
Word exports HTML designed to round-trip back into Word: it is bloated with proprietary classes and inline styles that fight any website’s design. Mammoth produces the opposite — minimal semantic markup your site’s CSS can style.
They are embedded directly in the HTML as data URIs, so the output is a single self-contained file that displays anywhere. For very image-heavy documents that makes a large HTML file; a CMS media library may serve you better there.
Structure and emphasis survive — headings, bold, italic, lists, tables, links. Exact fonts, sizes and page layout do not, by design: the web page’s own styles should decide presentation.
Mammoth reports Word features it mapped differently or skipped — an unusual style, an exotic element. They are informational; the preview always shows the true result.
No. The conversion runs entirely in your browser; your documents never leave your device.
